“I just wanted to thank you for the awesome hot chocolate hike last weekend.  My kids had such a great time and really enjoyed the afternoon.  And I must say that even I learned a lot…as a 43 year old woman still learning things about nature was really cool!  We love the arboretum and my kids have really enjoyed the camps and spring break weeks and all the special events that you provide throughout the year, so a big thank you to you and the entire arboretum staff for such fun and informative programming.  Hope to see you again soon on the next hot chocolate hike!”
